Chemical Composition and Mechanical Properties of The Main Series of Extruded Aluminum Alloys
Aluminum alloy, often referred to as extruded, is a type of light alloy with a relatively small density and strength. Its hollow spaces, which are created by molten aluminum, allow for a relatively low weight and low production costs. It is used in various applications ranging from construction, transportation, aerospace, and automotive industries to garage door frames, window frames, and aircrafts.
The most commonly used aluminum alloys are EN AW 6005A and the increasingly popular EN AW 6082. EN AW 6005A is an aluminum alloy with a surface finish that offers great corrosion resistance. This material is also ideal for cold forming, bending and welding. It also has a relatively low cost and is used in many different types of construction and automotive applications.
EN AW 6082 utilizes a surface finish that offers high strength and good weldability. It is ideal for applications that require high strength, good weldability and surface finishes that resist corrosion. It is used in the extrusion, anodizing and surface treatment of structural components.
The main series of extruded aluminum alloys have a wide range of mechanical properties and chemical compositions depending upon the alloy system and intended application. These alloys typically contain the elements aluminum, copper, magnesium, manganese, zinc, and silicon. The chemical composition of these alloys are expressed in alloy systems and lithium, titanium, and chromium can also be present in small percentages.
The main series of extruded aluminum alloys have a range of mechanical properties across the various alloy groups. These mechanical properties include yield strength, tensile strength, ultimate tensile strength, modulus of elasticity, and elongation at break. The yield strength is the point at which an applied load causes permanent material deformation, while the ultimate and tensile strength is the maximum load the material can withstand prior to failure. The modulus of elasticity defines the ratio of stress to strain within the material, and is a measure of stiffness. The elongation at break is the amount a material can be stretched before fracture.
Alloys from the extruded aluminum alloy family are often chosen based upon the intended application. The mechanical properties and chemical composition can vary greatly depending upon the type of alloy and intended use. For example, EN AW 6082, which has a high strength, is often used for automotive, aerospace, and structural applications, while EN AW 6005A with its lower strength is more cost effective and used for industrial applications.
Finally, extruded aluminum alloys are easy to handle, form, and weld and provide an ideal solution for applications that require corrosion resistance, good surface finishes, weldability, and light weight. With the wide range of alloy systems and chemistries, these alloys provide a reliable solution for many different types of applications.
